1.) A most vile concoction. Where one mixes Kool Aid powder with their preferred energy drink (Rockstar, Monster, etc...). Alcohol may also be added, but is not suggested as even one shot of alcohol added to the already lethal amounts of caffeine will make a drink stronger than a four loko.

2.) Basically, Crystal meth in liquid form.

Damn, I wanna try something stronger than weed, but I don't wanna shoot or snort anything.
